Residents and local exercise lovers are still reeling a week on from the killing of jogger Joanne Pert in a Remuera street, Cherie Howie reports.

Philip Oldham had his hands on the wheel and his eyes on the road. Now, he has guilt in his heart.

Ten days ago he backed out of his driveway on the corner of Victoria Ave and Shore Rd, in the upmarket suburb of Remuera, and began the short drive across the Waitemata Harbour to the North Shore. It was some time after 9.30am.

Three doors down, just before 11am, Auckland woman Joanne Pert was discovered slain on the lawn of a stranger's house. Police believe she may have been there as long as an hour, and the thought of the mum-of-two suffering just out of his line of sight as he drove past haunts Mr Oldham.

A phone call from his wife, Susan, alerted the 68-year-old to the tragedy. He's hardly stopped thinking about it since.

"I'd been through there, right when it probably happened, and then you think 'crikey, if I'd been more vigilant, maybe I could have saved her'. It's just shocking ... she was an innocent passerby, she wasn't doing anything wrong."

Susan Oldham also carries the burden of "what if?" She was home - only 50m away - at the time Ms Pert died. She wished she could have helped her.

It's seven days since Ms Pert's death when the Weekend Herald visits, but the shock of her horrific fate is still raw along the busy thoroughfare where her 41 years of life came to an end.

"I just feel a deep sense of sadness," says Susan Oldham, who now baulks at leaving the house for her regular walks.

"The futility of taking away someone who had a reason to be here, she had kids to bring up ... grief is a bit like guilt, in a way. It hangs around."

Ms Pert was an ordinary person in an ordinary street when she died in the most extraordinary circumstances.

Her death was hidden from view. But, she wasn't alone - far from it.

Shore Rd, with its mature heritage trees and proximity to the Hobson Bay Walkway, teems with those who lace up in search of a double shot of mental and physical wellbeing.

Just ask Philip Oldham. A police officer, who knocked on the door the day of Ms Pert's death to ask if he or his wife had seen a woman in exercise gear, was left in no doubt as to just how many people pound the pavements in the neighbourhood.

"I said 'yes, about 400 a day'."

The Weekend Herald spoke to many of those who exercise in the area, all determined not to let a senseless death stop their way of life. But that's not to say they aren't afraid.

A middle-aged jogger spoke of regularly running in the Shore Rd area each morning - except on the day of Ms Pert's death, when she overslept.

"I'm extremely upset about this, it was so close to me. A friend said to me 'you might've been able to save her'. It's certainly rattled me."

Pensioner John Cozens lives near Shore Rd and walks his chocolate labrador, Sienna, along a 5km route in the area every day. He can hardly believe what happened, and that it occurred in the bright sunlight of a summer's mid-morning.

"I just thought 'what the hell is going on around here?' I don't understand why someone would do something like that."

"It was the most random event at the most random time. It was a big surprise."

But he is determined not to succumb to fear.

"It can happen anywhere, it just reinforces that you never feel totally safe. You can't [make peace] with that ... life goes on."

• A 24-year-old Mt Roskill man handed himself in to police the day of Ms Pert's death, and was subsequently charged with her murder. The man, whose name is suppressed, was remanded in custody until his next court appearance.
